EDWARD W. JOHNSON, 0F HUNTINGTON, WEST VIRGINIA, ASSIGNOR 0F ONE-FOURTH TO JAMES K. ONEY, OF HUNTINGTON, WEST VIRGINIA.

EGG-TESTER.

Specification of Letters Patent.

Patented Oct. 3, 1916.

To all whom it may concern:

Be it known that I, EDWARD IV. JOHNSON, a citizen of the United States, residing at Huntington, in the county of Cabell, State of Vest Virginia, have invented certain new and useful Improvements in Egg-Testers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in egg testing machines.

One object of the invention is to provide a simple and novel device of this character which is particularly adapted for testing eggs for incubator use, the same being adapted to be readily moved up to the incubator so that the egg tray can be readily withdrawn from the incubator and quickly placed on the tester.

Another object is to provide an egg testing device in which the light will be more readily diifused and softened so as not to hurt the eyes of the user.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing, and in which:

Figure 1 is a top plan view of my egg testing machine, Fig. 2 is a transverse sec tion on the line 2-2 of Fig. 1, Fig. 3 is a fragmentary horizontal section on the line 33 of Fig. 2, and Fig. 1 is a longitudinal sectional view on the line 4.4 of Fig. 1.

Referring particularly to the accompanying drawing, 10 represents a cabinet supported by the legs 11 which are provided with suitable casters 12. This cabinet is opened at the top and one end is provided with a hinged door 13. Mounted in the cabinet and extending longitudinally are two downwardly and inwardly converging walls 14, the upper edge of which are secured to the side walls of the cabinet while the lower ends are secured together. A strip of suitable material 15, which is triangular in cross section is secured in the angle at the lower ends of the walls 141 and supports on its upper face a narrow strip of transversely corrugated mirrored glass 16 which extends the length of the walls. Mounted on the inner faces of the walls 14: are the inclined mirrors 17. Mounted on the end wall of the cabinet opposite to the door is a lamp socketlS which carries a suitable electric lamp bulb 19. A block 20 is secured at the door end of the walls 1 1 and supports a second lamp socket 21 carrying an electric lamp bulb 22. Suitable electrical conductors 23 are connected to the lamp sockets and are provided with a screw plug 21 adapted to be engaged in the ordinary electric lamp socket. In the inner faces of the vertical walls of the cabinet just above the upper edges of the walls 14 are formed grooves 25 in which is slidably engaged a sheet of ground glass 26. Removably disposed on the cabinet above the ground glass is a tray 27 having a reticulated bottom on which the eggs to be tested are placed. A cloth hood 28 is placed above the tray and the operator inspects the eggs through an opening formed in the upper end of the hood. By providing the ground glass, the light from the lamps is considerably softened and dif fused so that it is less trying on the eyes of the operator than were a clear transparent piece of glass used. The corrugated strip of mirror together with the inclined mirror considerably strengthen the light that emanates from the lamp.

What is claimed is:

In an egg tester, a portable cabinet having an open top and a movable door at one end, downwardly converging walls mounted within the cabinet, mirror plates supported against the inclined walls, the lower edges of the mirror plates being spaced apart, a strip of corrugated mirrored glass disposed between the spaced ends of the first-named mirrors, lamps mounted above the corrugated mirror, and a sheet of ground glass removably disposed in the open top of the cabinet.

In testimony whereof, I afiix my signature, in the presence of two witnesses.

EDWARD WV. JOHNSON.
